Analyzing Seat Transitions
When analyzing election results, it is important to distinguish between a change in the individual representative and a change in the party representation. For the purposes of tracking political shifts, a seat is only considered to have changed allegiance if the winning party differs from the party of the previous incumbent.
The Role of By-Elections
By-elections are special elections held to fill a vacancy in the House of Commons between general elections. In the context of the 2015 results, some constituencies had changed parties during a by-election but were subsequently won back by the original party on 7 May. These instances are recorded as changes in allegiance to reflect the volatility of the seat leading up to the general election.

| Party A replaces Party B | Yes | Change in political allegiance. |
| Party A replaces Party A (New Person) | No | Party allegiance remains the same. |
